Hi Carrie, the hot weather used to aggravate the heck out of my small nerves, nerve's healing can go a crazy too its hard to tell the differance at times but i found it normally followed by very slight severity of symptoms, there was no certain pattern of the amount of time they would flare for though.
I was told by a Gp that has spent decades practicing Accupunture that it would not help or repair my small nerve damage, i know its fantastic for muscel spasms and heaps of other complaints, sorry i don't know anything about NAET.
Can you see your doc to see if you can adjust your meds or add another whilst you are going through this hard time ? sometimes we can build up a tolerance to certain drugs and they don't seem to work as good as before.
good luck
Brian
